well it has been about 4 months but now is good......gg aus found the wrong power valve had been fitted and rectified that for no real gain....so, many emails and phone calls later the complete engine was sent to the gg dealer in Holland ( who sets up the wec bikes ) ...... ports were all over the place, crank was out of balance, cases were'nt matched, timing could not be set correctly, squish was out. After all of this was rectified the end result according to gg is 42 HP. I am not going to dyno it myself because it is SO much better now, but I have since added a DEP silencer and set the jetting at...N1EG needle 3rd clip / 178 main jet / 45 pilot, with the last thing to be done, an oversize power valve cover which is on back order.
I AM HAPPY AT LAST ( although a year older )
cheers

John at gasgas Australia paid for the freight to Holland and Wim at Oerlemans Offroad Shop provided the service free of charge, I was just lucky that my concerns of poor performance were noted after the first ride in July 2008.
PS, none of my emails to Spain have ever been answered, thanks must go to John as he has never doubted my complaints.
Cheers
Perhaps you could post the address and a name or two of the dealer in Holland who did the work. It sounds like they are very good.
